The most common use cases for the Vainu APIs:
Following our API-first philosophy, the Vainu APIs are the first places to get your hands on new datasets. Moreover, some datasets are only available through the APIs and not in our platform's UI.

Empower your teams across functions by giving them access to meaningful company information: Display the data they need in any system in use with a custom or our ready-made iframe solution, Vainu View.
Track important company-level changes
Help your teams take action upon company changes in their target accounts as they happen. Whether it's about a company appointing a new CEO, raising a round of funding, or announcing plans to grow internationally, you can seize these moments using our Signals endpoint or webhooks.

Bring company data to PowerBI, Tableau, QuickSight, Qlik, and similar platforms. Most BI platforms accept data entries in JSON and CSV formats. Vainu API returns the data in both CSV and JSON formats.
